TLDR
In this article, a room-temperature motion sensor with record sensitivity was created using a levitating silica nanoparticle and feedback cooling to reduce the noise arising from Brownian motion enables a detector that is perhaps even sensitive enough to detect non-Newtonian gravity-like forces.Abstract:

Interaction between an Optically Levitated Nanoparticle and Its Thermal Image: Internal Thermometry via Displacement Sensing
TL;DR: In this article , displacement sensing of an optically levitated nanoparticle in front of a surface can be used to measure the induced dipole-dipole interaction between the nanoparticle and its thermal image.
Theory of phase-adaptive parametric cooling
TL;DR: In this paper , an adaptive phase technique for the parametric cooling of mechanical resonances is proposed, which involves the detection of the mechanical quadratures, followed by a sequence of periodic controllable adjustments of the phase of a parametric modulation.

Steady state of overdamped particles in the non-conservative force field of a simple non-linear model of optical trap
TL;DR: In this paper, an exact solution for the steady state statistics of an overdamped Brownian particle subjected to a commonly used force field model for an optical trap is presented, which is the simplest of its kind that takes into account non-conservative forces.

Single spin detection by magnetic resonance force microscopy
TL;DR: The long relaxation time of the measured signal suggests that the state of an individual spin can be monitored for extended periods of time, even while subjected to a complex set of manipulations that are part of the MRFM measurement protocol.

Zeptogram-Scale Nanomechanical Mass Sensing
TL;DR: Analysis of the ultimate sensitivity of very high frequency nanoelectromechanical systems indicates that NEMS can ultimately provide inertial mass sensing of individual intact, electrically neutral macromolecules with single-Dalton (1 amu) resolution.

A nanomechanical mass sensor with yoctogram resolution
TL;DR: This unprecedented level of sensitivity allows us to detect adsorption events of naphthalene molecules, and to measure the binding energy of a xenon atom on the nanotube surface, which could have applications in mass spectrometry, magnetometry and surface science.

On the Resistance Experienced by Spheres in their Motion through Gases
TL;DR: In this article, the authors derived the force exerted by the impinging molecules leaving the surface depending on how they leave, assuming the usual Maxwellian distribution of velocities in the gas, the force was found to be M where M=(4π/3) Nma2cmV, N, m, a, and V being the number per unit volume, mass, radius, and mean speed of the molecules and V the speed of a droplet.
